hello, guys. I want to get the image data in the camera preview. I know that it is now permitted to use the undocumented API UIGetScreenImage(), however because in my custom ImagePicker, there is a overlay view to show some info to the user, and UIGetScreenImage returns whatever in the screen including the overlayView, But I simply want to get the data which the camera "see",as takePicture returns. So, is there an way which can pass appstore review to achieve it? Thanks in advance.
